Allgemeine Beschreibung

Red-Gal is a chromogenic substrate for β-galactosidase, used to determine the presence or absence of a cloned DNA insert in bacteria growing on agar plates. Red-Gal is designed to replace X-Gal in blue-white selection of recombinant bacterial colonies with the lac+ phenotype.
Red-Gal is a chromogenic substrate for b-galactosidase,[1] used to determine the presence or absence of a cloned DNA insert in bacteria growing on agar plates. Red-Gal is designed to replace X-Gal in the blue-white selection of recombinant bacterial colonies with the lac+ phenotype.

Anwendung

Chromogenic substrate for β-galactosidase producing a red or magenta insoluble product.
Magenta-Gal has been used for staining synthetic cytoplasmic or nuclear LacZ mRNA.[2] It has also been used to detect the expression of the EphB1-β-gal fusion protein.[1] ,Magenta-Gal is suitable for use in the selection of recombinant bacterial colonies with the lac+ phenotype.

Prinzip

When Red-Gal is hydrolyzed by β-galactosidase, the resulting product will form a red precipitate. Lac+ colonies grown in the presence of Red-Gal turn an intense red color, allowing for easy differentiation between lac+ and lac- colonies.

EphB receptor tyrosine kinases direct axonal pathfinding through interactions with ephrin-B proteins following axon-cell contact. As EphB:ephrin-B binding leads to bidirectional signals, the contributions of signaling into the Eph-expressing cell (forward signaling) or the ephrin-expressing cell (reverse signaling) cannot be
